After yet another school shooting, a 14-year-old boy is in custody after shooting a classmate in the arm this morning.

The shooting is markedly different from previous incidents in the U.S. in that the student chose to use a rifle rather than an automatic assault weapon.

Authorities took the shooter into custody this morning about a mile away from the high school in a grocery store parking lot.

The school remained under lock down until 10:30 a.m., when students were finally released and reunited with their families.

The most deadly school shooting this year happened in Parkland, Florida on Valentine’s Day, and triggered a wave of threats against other schools throughout the nation.

In just nine days following the Parkland shooting, Los Angeles Unified School District police received more than 160 threats, resulting in at least one arrest of a student who threatened to shoot up the school after a teacher confiscated his earphones.

The student was found to have two semiautomatic rifles, two handguns, and 90 high-capacity magazines in his home.

The student’s brother, a U.S. Army veteran, claimed the weapons were his.
